What is the BMW SVS module?

SVS stands for the voice recognition system. SVS is integrated into the CCC (CIC) unit located in the dashboard. It processes language input from voice commands.

SVS's main function is to control the various vehicle functions using voice commands.

BMW SVS can be used to control the following systems:

  • Entertainment
  • Communication
  • Navigation
  • Air conditioning Settings

When your BMW SVS module fails, you will no longer be able to use voice commands.

Diagnose SVS module

If you are experiencing problems and can no longer use voice commands, read codes from the SVS module. For this step, you will need a BMW diagnostic scanner that is capable of reading fault codes from the BMW SVS module.
